Solution
- Warning! Only to be carried out by authorized service personnel:
Carry out an internal test on the device to check the plug-in connector for the motor.
- Plug in contact thermometer/temperature sensor.
- Replace faulty connecting cable, plug, or contact thermometer.
- Switch off and switch on again after about 1 minute.
When fault is indicated again, please contact with IKA
